===Forearm Supination/Pronation===
The neutral position for the forearm is the
thumbs up position. When the hand and
forearm face the ceiling, the forearm is rotated
to approximately 90 degrees of supination.
Conversely, when the forearm faces down, it
is in approximately 90 degrees of pronation.
According to both the '''American Medical
Association (AMA) and the American Academy
of Orthopaedic Surgeons (AAOS), the normal
range of motion (ROM)'''<u>Underlined text</u> for both forearm supination
and pronation is 80 degrees.
===Wrist Flexion/Extension===
The neutral (0 degree) position of the wrist
is the fingers straight and the hand aligned
with the forearm. Flexion at the wrist involves
movement of the palm of the hand toward the
palm side of the forearm. In colloquial bowling
speak, this has historically been referred to as
cupping the ball. Wrist extension is moving
the fingers and palm away from the palm side
of the forearm. Extension is often referred to
as breaking the wrist. The normal ROM for
wrist flexion is 60 degrees (AMA) to 70 degrees
(AAOS). According to the AMA, the normal
ROM for extension is 60 degrees whereas the
AAOS reports it as 70 degrees.
===Wrist Ulnar Deviation/Radial Deviation===
Ulnar deviation is moving the wrist medially,
toward the body. It is named for the ulna bone,
a long bone on the inside (when the forearm is
supinated) of the forearm. This is also known
informally in bowling circles as cocking. Both
the AMA and the AAOS rate the normal ROM
for ulnar deviation as 30 degrees. Radial deviation
moves the wrist laterally, away from the
body. The radius bone is located on the thumb
side of the forearm and is also a long bone in
the forearm. The normal ROM according to
both the AMA and the AAOS is 20 degrees.
===Elbow Flexion/Extension===
Elbow flexion is moving the forearm toward
the upper arm and body. Extension refers to
the movement away from the upper arm and
body. In the set up of most bowlers, the forearm
is supinated and flexed at ninety degrees
or higher of elbow flexion. The AAOS states
that the normal ROM is 150 degrees with 140
for the AMA. The neutral or zero position is
the arm fully extended.
===Trunk Lateral Flexion===
Lateral flexion is leaning or bending the
trunk to the side. For bowling, in the modern
game, in order to establish an improved line
of sight and space for the swing slot, lateral
flexion is a critical element of an efficient
game. The neutral or zero position would
be standing straight. The normal ROM for
the lower (lumbar) and middle (thoracic)
spine is 30 to 35 degrees. In the October
2010 Slowinski at-large, I discussed the body
position in which trunk lateral flexion helps
create space for the swing slot as well as enhancing
torso rotation.
===Shoulder Extension/Flexion===
In bowling terms, shoulder flexion
(forward) and extension (backswing) are
an important component of the physical
game. The neutral position of shoulder
extension or flexion is at the side, adjacent
to the leg. With the arm in front of the
body, the shoulder is flexed slightly. Flexion
is forward movement with a normal ROM
of 150 (AMA) or 180 (AAOS). The normal
ROM of extension is 50 (AMA) or 60 (AAOS)
degrees. Pay special attention to the normal
ROM in regard to shoulder extension. The
height of the swing can only be achieved by
trunk flexion.
===Shoulder Adduction/Abduction===
Abduction is to move the upper arm away
from the body. Adduction is to move the upper
arm toward your body.
===Trunk Flexion===
The normal ROM for the lower (lumbar)
and middle (thoracic) spine is 80 (AAOS) and
60 (AMA) degrees.
Trunk Rotation
Some bowlers rotate the torso which places
the ball-side hip and shoulder behind the balance
arm side hip and shoulder.
===Knee Flexion===
Bending at the knee is knee flexion. The
normal ROM is 135 (AMA) or 150 (AAOS).

7 Exercises Every Bowler Should Know by Pete Williams September 2, 2011


Tom Blasco's Expert Bowling Tips

As one of Bowler Journal's Top 100 Coaches 2005 through 2009, the owner and operator of Bowler's Corner in Satellite Beach, FL since 1975 and the member of bowling's leading organizations Tom hardly needs an introduction.

Tom offers expert tips primarily geared to other bowling coaches but are also useful to amateur bowlers.


Grip Test as illustrated by Don Johnson

This is something illustrated by Don Johnson on his first video "A Pro's Guide to Better Bowling Volume 1, it is a "test" to see if the thumb-hole is too loose or too snug. http://www.bowlingbookstore.com/products/94

Requirements: the ball, some bowlers tape, a tool to add or remove tape. Caveat: the objective of this test is for the ball to drop off the thumb following an action an assistant will perform. A bowler could do this solo. The bowler can be standing up or kneeling down so the ball does not fall far!

Before performing the test, the bowler should check the ball to see if the ball is obviously too tight or too loose. Adjust the fit if needed.

Once the bowler thinks it fits well, the bowler should insert their fingers and thumb in the ball as per norm.

Next, the bowler should hold the ball down by their bowling side in a collapsed wrist position. Definition: Collapsed wrist in this context is like you would position palm to push yourself away from the table or on the floor to do pushups. The bowlers palm should be facing towards the floor and the ball should stay on because you've already checked to see if it was too loose. If it does slip off, add tape. If it stays on, the assistant should position their hand on the back of the bowlers bowling hand (the flip side of the palm). Now press down and straighten out the bowlers wrist. If the ball stays on, the thumb is too tight ( adjust the thumb hole tape ) If the ball easily drops off, the fit is good, this is what we are looking for.
